Titanium Dioxide 1.6% ●
TL;DR. This ingredient functions mainly as a mineral pigment and opacifier, adding whiteness, coverage, and visual opacity. At 1.6%, it is more likely serving appearance or tone-correction than acting as the primary UV-screening active.
What does Titanium Dioxide 1.6% do in a cosmetic formula?
This ingredient functions mainly as a mineral pigment and opacifier, adding whiteness, coverage, and visual opacity. At 1.6%, it is more likely serving appearance or tone-correction than acting as the primary UV-screening active.
Is Titanium Dioxide 1.6% clean?
From a clean-beauty perspective, it is broadly accepted in creams, lotions, makeup, and sunscreens, with the main scrutiny focused on inhalable powders, sprays, and particle-size labeling. Dermal tolerance is generally good because it is inert and not a common sensitizer.
Is Titanium Dioxide 1.6% sustainable?
This material is mineral-derived and requires mining plus energy-intensive purification and milling. It is not biodegradable, but it is an inert inorganic solid and does not behave like a petrochemical that breaks down into smaller organic residues.
Is Titanium Dioxide 1.6% COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when the grade meets mineral-ingredient and, where relevant, particle-size requirements. Its Green Chemistry fit is mixed, since it is naturally derived and chemically stable, but non-renewable, mined, and not biodegradable.
How does Titanium Dioxide 1.6% work chemically?
This compound is an insoluble inorganic crystalline solid with a high refractive index, which explains its strong whitening, coverage, and light-scattering behavior. It is stable across normal cosmetic pH ranges, is often surface-treated for dispersion, and may be used from low single digits for opacity to much higher levels when formulated as a regulated UV filter.
